Sea waves energy converter

ABSTRACT

The conversion of wave energy in electrical or mechanical power is disclosed by means of the present subject-matter. When the sea wave is pushing up the floating cylinder ( 1 ) the transporter arm ( 2 ) is retracted in the sealed box ( 3 ), which converts the linear motion of transporter arm ( 2 ) by means of a chain belt ( 11 ) and a sprocket ( 8 ) m a rotational motion, when down the potential energy in the moving parts pull the transporter arm ( 2 ) which converts the linear motion into rotational motion by means of chain belt ( 11 ) and sprocket ( 7 ) in the same direction.

TECHNICAL FIELD

-   -   Producing electricity from sea waves     -   Design new Boats working without fuel     -   Emergency generator for sea vessels

BACKGROUND ART

-   -   Water Turbine based on difference in head     -   High and low tide     -   Underwater buoyant device     -   Overtopping device (water turbine base)     -   Oscillating water column     -   Floating device (two floating device hinged together)

DISCLOSURE OF THE INVENTION

It is a mechanical device consists of

-   -   1—Floating cylinder     -   2—Transporter Arm     -   3—Sealed Converter Box     -   4—External cylindrical wire mesh

Its function based on two phenomena:

-   -   Gravity     -   Buoyant force (Archimedes)

It works like the motion of the Internal Combustion Engine but.

-   -   1—with active up and down stroke     -   2—with a very flexible stroke length (synchronized with the wave         amplitude)

When the sea wave is up it push the Floating cylinder—1—(buoyant force) See drawing no. 1/11 whish push the Transporter arm—2—throw inside the Sealed Converter Box—3—which convert this linear motion into rotational motion clockwise, when the wave come down the weight of the movable mechanical parts and the arm—2—moves down by the Gravity Force inside the box—3—converting this motion into rotational motion in the same direction clockwise, then the rotational motion transport throw the rod—12—to the small flywheel—13—, the external wire mesh—4—saves the Floating cylinder—1—in a position under the arm—2—because of the free connection between them. (See drawing no. 1/11 and 5/11)

If we consider one converter as one cylinder (in an Internal Combustion Engine) so we can pout any number of converters in one station accumulated together electrically or mechanically to get the power we need. (See drawing no 8/11, 9/11)

Not: The movable mechanical parts is—2—, —10—(sea drawing no. 3/11) and the extra weight—23—if needed (see drawing no. 5/11)

Sealed Converter Box:

It consists of the following parts (NOT the serial numbers as the drawing no. 2/11, 3/11)

-   -   5—Driven ratchet gear     -   6—Negative ratchet gear (just for holding chain belt—11—in a         vertical position and rotate negatively in clockwise direction     -   7—Tension ratchet gear (it is locked in clockwise direction) in         down stroke and negative (rotate free in anticlockwise         direction) in up stroke(or ratchet lever loaded in down stroke         and unloaded in up stroke see drawing no. 6 part—77—as         alternative solution)     -   8—Tension ratchet gear (it is locked in clockwise direction) in         up stroke and negative (rotate free in anticlockwise direction)         in down stroke (or ratchet lever loaded in up stroke and         unloaded in down stroke see drawing no. 6/11 part—88—as         alternative solution)     -   9—Metal wheel to guide the chain belt—11—in a fit position with         the two gears—7—, —8—     -   10—Holder to hold —7—, —8—, —9—attached together to insure them         working together and it is fixed with the transporter         arm—2—11—Chain belt whish transmit the linear motion from the         holder—11—to the gear—5—, —6—

How it Works:

-   In the off condition (sea drawing no. 9/11) before starting the     station which consists of more than one converter the Transporter     Arm—2—is locked in the upper position (dead point) which makes the     floating cylinder—1—moves up and down freely inside the cylindrical     wiremesh—4—(unloading condition) -   By using an external starting motor to start up the station just to     come over the inertia of the flywheel—18—so we have the following     condition. -   Gears—5—, —6—rotate in clockwise direction, gears—7—, —8—rotate     anticlockwise direction freely (negative motion), wheel—9—rotate in     clockwise direction guiding the chain belt—11—moving safety inside     the gears—5—, —6—, the holder—10—and the transporter arm—2—(fixed     together) stay in its position without moving (dead point position)

Because the transporter arm fixed in that position far away from the floating cylinder.

-   -   3—When we release the transporter arm—2— it will take the         position according to the level of the floating cylinder—1—and         it will move up and down (synchronized with the wave amplitude)

Working Condition:

When the sea wave is coming up it will push the floating cylinder—1—then the transporter arm—2—and the holder—10—upward so gear—8—in a lock condition (not rotate in clockwise direction) so it results the tension T1 (see drawing no. 2/11) which enforce gear—5—to rotate in clockwise direction so the rod—12—and flywheel—13—which deliver the motion to the rod—17—(see drawing no. 9/11) and finally to the flywheel—18—then to the generator while gear—7—rotate anticlockwise When the sea wave is coming down it will pull the transporter arm—2—and the holder—10—downward so gear—7—in a lock condition (not rotate in clockwise direction) so it result the tension T2 (see drawing no. 2/11) which enforce gear—5—to rotate in clockwise direction then the rod—12—and flywheel—13—which deliver the motion to the rod—17—(see drawing no. 9/11) and finally to the flywheel—18—then to the generator while gear—8—rotate anticlockwise.

So any movement of the sea wave with any amplitude up and down it result a rotational motion in one direction

Not: if we consider the energy needed from one converter is E1 and the gravity energy whish results from the moving parts during downward is E2 and the energy results from the buoyant force is E3.

So E2 must be>E1. And E3 must be >(E1+E2).

By accumulating numbers of converters together we can decrees E2 (the weight of the moving parts) to a certain limit.

Alternative Holder:

We can replace holder—10—by another one as drawing no. 6/11 which indicate to the ratchet levers system

Increasing No. of Holder:

According to design parameters we can increase the numbers of holders as drawing no. 4/11.

Drawing no. 5/11 indicate to the free connection between floating cylinder—1—and the transporter—2—because of the erection purposes, (on and off conditions), maintenance, mechanical vibration and others.

-   -   Near to the beach (see drawing no. 8/11, 9/11) —19—indicate to         the sea wave     -   On the beach (see drawing no. 10/11) in which—20— indicate to         the beach mountain, —19—indicate to the sea wave, —15—is the         concrete skeleton, —16—is a station room and —21—is a beach         rocks     -   On sea vessels (see drawing no. 11/11) —22—indicate to the sea         vessel (FIG. 1 is on condition and FIG. 2 is an off condition)
